综述了近几年来关环复分解(RCM)反的研究新进展,包括了烯烃、烯-炔的RCM反。
2.In this thesis, the carbozincation of acetylenic sulfones and its applications in the stereoselective synthesis of polysubstituted olefins were investigated.
本论文研究了炔基砜的碳锌化反及其原位产生的α-磺酰基烯基锌试剂在立体选择性合成多取代烯烃中的用。
3.The diolefins and alkenyl aromatics are very unstable components which can give gums by polymerization.In giving olefins and alky aromatics the hydrogenation improves the product quality.
